WILLARD M. FLYNN', OF WATERLOO. IOWA.

I HOG-OILER.

Application filed July 29, 1916.

To all whom it may concern:

Be it known that I, l/VILLARD M. FLYNN, a citizen of the United States of America, and a resident of WVaterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Hog-Oilers, of which the following is a. specification.

My invention relates to improvements in hog-oilers, and the object of my improve ment is to supply means for exteriorly applying a medicinal fluid to an animal operated by contact to furnish a limited quantity at each service and adapted to automatically return to its first or re-filling condition when the contact has ceased.

Other improvements will be more specifiv cally pointed out hereinafter.

These improvements I have accomplished by the means which are described herein, and which are illustrated in the accompanying drawings, in which, Figure 1 is an elevation of my improved hog-oiler; Fig. 2 is an upper plan view of the reservoir with the oil-delivery apparatus removed; Fig. 3 is an enlarged cross-section of said reservoir, its supply-tank, and the upper part of one of the delivery-bars, with parts broken away or removed; Fig. 41 is a detail view of the oildelivery means, with the invertible dipper or cup shown in central longitudinal section, and Fig. 5 is a perspective detail view of said oil-delivery means.

Similar numerals of reference denote corresponding parts throughout the several views.

The numeral 18 denotes a triangular reservoir, open at the top and having a central dependin tubular socket mounted on the upper end of a tubular standard 21 and secured detachably thereon by means of a setscrew 20. The lower end of said standard is mounted in a tubula socket 23 integral with the tripod 24:, whose feet are bolted to a beam or other fixed support 25.

The bottom of said reservoir has three rectangular openings having marginal walls 17 extending into the reservoir only part way to its top.

The numeral 27 denotes a supply-tank imperforate except for a central port in one head having a raised rim 31 whose outer part is funnel-shape and through which the tank may be filled with any medicinal fluid, such as petroleum or other fluid.

Within said tank is a frusto-conical closure 30 mounted on a stem 29. The upper Specification of Letters Patent.

end of said stem moves through an orifice in a spaced bracket 28 fixed on the inner face of the head opposite the head containing said funnel, while the other end of the stem is passed centrally through the funnel to ex tend therefrom a distance. l/Vhen the tank is filled with fluid and inverted the closure 30 will drop and close the funnel, but when the tank is'positioned upon the top of the reservoir 18 in its inverted position, the stem in contacting with the bottom of the reservoir, as shown in Fig. 3 moves up and dislodges the closure 30, permitting the fluid to pass into the reservoir to a certain constant level, due to the action of the air-pressure on its surface and because of the vacuum in the tank above its fluid contents.

The numeral 9 denotes a channeled bar whose lower end has a pair of lugs which are pivoted at 22 to a lug on the pedestalsocket 23. There are as many of these bars 9 as reservoir ports 17 and they are alike in form and dimensions and all serve the same purpose, so I shall limit my description to one of the bars and its connected fluid-delivery means.

To the diminished upper part 8 of the bar 9 which extends upwardly into the reservoir through a port 17, is pivoted at 7 two spaced arms of a linking-connection 6, having an integral cross-bar 10 and also two spaced angularly-disposed arms 5. Between the arms 5 an invertible dipper or cup 1 is pivoted on pintles 4:. Into the interiorly-threaded lower end of said cup is inserted an adjusting-screw, which may be adjusted to vary the contents of the cup as desired. One side of the cup is partially cut away, while the opposite side of the cup has an orifice or delivery-opening 3.

The bar 9 is pivotally supported to be positioned at one side of its center of gravity, and when in its lower position shown in Fig. 3 in full lines, its linking-connection 6 drops so as to lower the cup 1 into the fluid in the reservoir, where it fills. When an animal rubs against the bar, the bar is swung upwardly toward but not quite to the vertical, as is indicated by the dotted lines in Fig. 3. In this movement, the rubbing contact of the arms 5 of the linkingconnection 6 swings said connection upwardly until the lifted cup 1 is tilted over to deliver its contents through the orifice 3. The bar 9 just below the diminished part 8 has an inclined surface 13 receiving from a hollowed channel 16 upon which the oil is delivered. The outer raised edges of said bar have a plurality of detents 12 upon Which the animal may rub, and the flattened channel between these raised edges is furnished with a plurality of spreading devices 1 1 and 15 which serve to keep the descending oil spread upon thesurf aoe of the bar and to prevent its too speedy descent. Oil or other fluid is prevented from escaping from the sides of the inclined plane 13, by means of lateral shields 11.

Then the animal moves on, releasing the bar 9,, the latter drops to its first position, thus causing the linking-connection, 6. to automatically rock back, lowering the cup 1 again into the fluid, where it is refilled and ready for another actuation.

By the use of this device, the fluid is conserved, and applied only as needed, while the parts act automatically inreturning to their first positions after actuation.

Various changes may be effected in the form, number, arrangement and details of the parts of my device, without departing from the principles of the invention or from the scope of its protection.

The supply-tank 27 is detachably mounted on the top. of the reservoir 18 and held from accidental displacement, by means of a plurality of rods or clips 26, whose inturned lower extremities are caught under the bottom of the reservoir, the upper ends of the rods being fixedly secured on the outer wall of the tank; the rods being resilient may be sprung out to release. the reservoir.

Having thus described my invention, what I claim as new, and desire to secure by Letter-s Patent, is: I

1. In combination, a reservoir, a tank supported in inverted position upon the reservoir to deliver its contents thereinto below a vacuum permitting the'maintaining of a constant level of fluid within the reservoir, said reservoir having a port in its bottom surrounded by raised marginal walls extending partly to. the top of the reservoir, a

barv mounted swingingly to be positioned to one side, in a limited movement, of its center of gravity, the upper end of the bar extending through said port, an angular link pivoted to the top of said bar, and a cup pivotally mounted above its center of gravity on said link, and adapted when'the bar is moved upwardly, to. drag over the marginal wall of said port, tilting, to deliver its contents downwardly upon the bar, said cup automatically being returned to its. first position Within the fluid in the reservoir for. refilling when the bar is released and returns under the influence of gravity to its first position.

2. In combination, a supporting standard, a reservoir mounted on said standard, pro,- vided in its bottom withfa port having marginal walls raised part way to the top of the reservoir, means for supplying fluid to said reservoir adapted to'maintain it at a constant level thereinlower than the height of the inarginal walls of said port, a bar pivoted to the base of said standard, its upper end extended through said port, an angular. linking-connection pivoted to. the top of said bar, an invertible cup, having a delivery-orifice in one side and pivotally mounted on said linking-connection, said bar having a bend below said port to sup ply an inclined oflz'set therein, and having fluid-spreading-ridges arranged on its surface below saidbend, said bar having roughened marginal ribs at each side of said spreading ridges, the bar when in its lowered position causing said linking-connection to. swing said cup into a. filling position in the fluid in the reservoir, and when moved to its upper position to cause the linking-connection to move. the cup across the marginal wall of the port, to thereby tilt the cup and cause it to. deliver its contents through its delivery-orifice upon the sloping oflset part of the bar, the bar re.- turning by gravity to its first lowered position when released.

Signed at lVaterloo, Iowa, this 12th day of July, 1916.
